Synthesis and photolysis of biphenylenetetracarboxylic dianhydride in low-temperature neon matrixes
Biphenylenetetracarboxylic dianhydride was synthesized by dimerization of benzynedicarboxylic anhydride generated quantitatively by laser photolysis in low-temperature matrixes. Synthesized dianhydride was used as a precursor of matrix photolysis. It was isolated in a neon matrix and photolyzed to form biphenylynedicarboxylic anhydride, a novel aryne species.
